HINGE.

SPECIFICATION forming part of Letters Patent N 0. 725,712, dated April21, 1903.

Application filed July 28, 1902. gerial No. 117,345. No model.) 7

To all whom, it may concern.-

Be it known that LRICHARD W. HUBBARD, a citizen of the United States,residing at Ashtabnla, in the county of Ashtabula and State of Ohio,have invented new and useful Improvements in Hinges, of which thefollowing is a specification.

My invention relates to improvements in hinges, more particularly thekind disclosed in my Letters Patent No. 586,663, of July 20, 1897; andit consists in the peculiar and advantageous hinge hereinafter describedand claimed, the sections or members of which are formed entirely ofsheet metal.

In the accompanying drawings, Figure 1 is a horizontal section takenthrough a door and door jamb and illustrating my improved hinge asproperly connected thereto. Fig. 2 is a perspective view of the hingeremoved. Fig. 3 is'a perspective view of the hinge as it appears whenopen and with the inner part of one section or member removed. Fig. 4 isa perspective view of said inner part. Fig. 5 is a detail transversesectiontaken in the plane indicated by the broken line 5 5 of Fig. 3.Fig. 6 is a transverse section taken in the plane indicated by thebroken line 6 6 of Fig. 1. Fig. 7 is a view of the sheet-metal blankfrom which the outer part of one section or member of the improved hingeis formed, and Fig. 8 is a View of the sheet-metal blank from which theouter part of the other section or member of the improved hinge isformed.

Similar letters of reference designate corresponding parts in all of theseveral views of the drawings, referring to which- A is one sectionormember of my improved hinge, B the other section or member, and O apintle which pivotally connects the sections or members A and B and hasa head or knob Ct at its upper end. The sections or members A Brespectively comprise an outer part D, an inner part E, and anintermediate part F, all of which are suitably formed of sheet metal,the blank from which the part D of section A is produced being shown inFig. 8 and that from which the part D of section B is produced beingshown in Fig. 7. The parts D are alike in that they have outer endportions 1) of concavo-convex, preferably semicircular, form incross-section and shoulders c at the inner ends of said portions 1); butthey differ in that while the part D of the section or member A has twobarrels d, with a space bGlJWQQIIHlGlI], the part D'of the section ormember B has but a single barrel e, said barrel 6 being designed to bearranged between the barrel d and, together with the same, receive thepintle C. The intermediate parts F of the sections or members A B arearranged at the inner sides of and curved in conformity to the endportions 1) of parts D, and they have finsf, which extend through slotsg in the portions b, Figs. 2 and 6. These fins are disposed-as shown inorder to enable them to cut into the wood diagonally across the grainwhen the hinge is driven into position, as presently described, this toprevent splitting of the wood and to hold the members A B in the woodincident to the driving of the hinge. The inner parts E of the sectionsor members A have angularly-disposed and rounded portions h at theirouter ends designed to rest flush with the outer ends of the parts D,curved lips 11 at their inner ends designed to enter under and conformto the barrels of parts D, and lateral projections j, shaped to enterthe recesses of the parts D back of the shoulders c. \Vhen the parts Eare arranged in the parts D of the sections or members A B in the mannershown and described, it will be seen that they will rest flush with theinner edges of the parts D, and in consequence the sections or members AB will respectively present the appearance of being formed in one piece.It will also be observed that when screws G are passed through thecoincident apertures in the parts E, F, and D and into a door anddoor-jamb to connect the sections or members A and B to said door anddoor-jamb said screws will serve the additional function of securing theparts E in the parts D. Y

When desirable,the parts E may be secured in the parts D by means otherthan the screws G-as, for instance, by brazingwithout involving adeparture from the scope of my invention.

In applying my improved hinge the door is fitted and placed in theposition in which it is to hang, and a hole is bored partly in thedoor-jamb (indicated by H) and partly in the door, (indicated by 1,) thefeed of the point of the auger-bit being started in the crack betweenthe jamb and door. A centering-plate J, Fig. 1, is then placed betweenthe sections A and B, and the hinge is driven into the hole byhammer-blows applied to the barrels, so that the finsf cut into the woodand hold the sections A B in place, after which the door is opened andthe screws G driven home.

It will be appreciated from the foregoing that by reason of the sectionsA B being formed of pieces of sheet metal said sections are susceptibleof being very easily and cheaply manufactured, also that the saidsections are strong and well capable of withstanding the usage to whichhinges are ordinarily subjected.

I have entered into a detailed description of the construction andrelative arrangement of parts embraced in the present and pre ferredembodiment of my invention in order to impart a full, clear, and exactunderstanding of the same. I do not desire, however, to be understood asconfining myself to such specific construction and arrangement of parts,as such changes or modifications may be made in practice as fairly fallwithin the scope of my claims.

2. As a new article of manufacture, a hinge section or member comprisingan outer, hollow part of. sheet metal, and an inner part of sheet metal,held in the hollow, outer part flush with the inner side thereof.

3. As a new article of manufacture, a hinge section or member comprisingan outer, hollow part, formed of sheet metal, and having a barrel orbarrels at one end, and an inner sheet-metal part held in the outerpart, flush with the inner side thereof and having a lip at one endengaging the barrel or barrels of said outer part.

4. As a new article of manufacture, a hinge section or member comprisingan outer, hollow part provided with a barrel or barrels,and also withlongitudinal slots, an inner part held in the outer part flush with theinner side thereof, and a part interposed between the outer part and theinner part, and having fins extending through the slots in the former.

5. As a new article of manufacture, a hinge section or member comprisingan outer, hollow part of sheet metal, having a barrel at one end, aforward portion of concavo-convex form in cross-section, and a shoulderin rear of said forward portion, and also having slots in said forwardportion, an inner part of sheet metal arranged in the hollow outer partflush with the inner side thereof, and having the angular and roundedforward end, and also having a lip at its rear end engaging the barrel,and a sheet-metal part disposed between the outer and inner parts, andhaving fins extending through the slots in the outer part.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
